Casino Bonuses (July 2026)
Last checked:
UK casino sites use a handful of common bonus types to attract new players. None of them are free money — each comes with terms that decide how, and whether, you can withdraw anything you win. Here's a plain-English guide to the main types, with a full explainer for each linked below.
Welcome bonuses
A match on your first deposit, sometimes paired with a set of free spins. The bonus funds typically carry a wagering requirement — a multiple of the bonus you must stake before any winnings can be withdrawn.
No deposit bonuses
A small amount of bonus funds or free spins credited just for registering and verifying your account, before you deposit anything. These tend to be smaller than deposit-matched offers and often carry higher wagering requirements or a maximum withdrawal cap.
Free spins
Spins on a specific slot game, awarded either with no deposit needed or as part of a deposit offer. Winnings from free spins are usually credited as bonus funds subject to wagering, rather than paid out as cash.

Playing safe
A bonus can encourage longer play than you planned, so it's worth setting a deposit limit and using session reminders before you claim one. GAMSTOP lets you self-exclude from all UK-licensed gambling sites at once if you ever need to. See our responsible gambling page for more.
